France, Britain and the U.S. conducted strikes on regime facilities in Syria. Explosions were heard and smoke was seen rising by witnesses from within Damascus. According to the Syrian Observatory for Human Rights, recently evacuated Syrian regime military targets and research facilities were hit.

Syrian propaganda state TV claims 13 missiles were shot down.

If anything, this should make Assad uncomfortable from conducting strikes on civilians for at least for the short time while America, Britain and France dominate their skies.

The U.K., U.S. and France each have a ship capable of missile launches in the eastern Mediterranean. The U.S. also has a submarine capable of launching tomahawk missiles there. There are more allied military assets stationed in nearby countries. This is considered minimal, but it was enough to conduct strikes.
